Our linvention relates to ba'l'l bearings.

One of the objects of our invention is to provide an improved oneipieceball retainer.

A further object of our invention is to provide an improved ballretainer which can be forced into osition after the balls have beenplaced in t e ball races.

A further object of our invention is to provide a. ball retainer whichermite of the alls being placed close togeter to enable practically afull set of balls to be used.l

A further object of our invention is to pro vide a ball bearingconstruction which will be simple, durable and eflcient.

Further objects will appear from the description and claims.

In the drawings, in which our invention is illustrated,

Figure 1 is a side view of a radial ball bearing;

Fig. 2 is a section on the line 2 2 of Fig. 3 is an edge view of theball retainer;

Fig. 4 is an enlarged fragmentary View of the ball retainer fingers;

Figs. 5, 6 and 7 are views showing different steps in the insertion ofthe ball retainer member.

Referring to the drawings in detail, the radial ball bearing showntherein com rises a set of balls 10, inner and outerihai race members lland 12 and a ball retainer 13 forholding lhi` hulls in posilion and inlproper .spaced relation. The balls and bal race members may be of anyusual or suitable construction, the principal novelty being in thc lmllretaining member and the manner in which it is combined with the otherelements.

This bull retaining member may be formed from :1 .single inlugral pieceol' material formed iulo :i cup-shape und with the sides of ihr cuppuni-hed out lo form Hexiblc linnn-rs l'i. the curved edges oi' whichfit over :ind i-nilirin-c lln balls in the ball race lo position lhviu:ind hold lluln in lhcir proper ri-lnliri, position. As shown in Fig. 4,the opi-niner IT lui-tween lu'o of these flexible lingrrs is oralrnlhcrlliun circular. The rea- `on l'or making llul opening oval iS lomake lluedges of lhe opening conform more closel lo the .surface ofthehall. As shown in Fig. T. thc linger is Iii-nl' at that. portion adjarrot tlubull so that :i round opening herivni-n who lingers would notlit the ball cl0sel) u hcrcus the oval opening does.

The balls are placed in position in any u'sualor suitable` 'manner as bypositioning the ball race member eccentrically with re- Spect to eachother and inserting all but a few of the balls, then positioning theball race member concentrically and inserting thc last few of the ballsby bringing the grooves 1li and 17 in the ball race member o posite eachother and inserting the balls tiirough the widened opening thusobtained.

Figs. 5, 6 and 7 show how the ball ref tainer is inserted into place.Fig. 5 shows the first step. When the hull retainer is pressed to theright, as shown in Fig. 5; tlfe i tips of the fingers will be forcedoutwardl by their engagement with the'ball and wi l extend over into theball race or groove 18 in the outer member. As the ball retainer isforced further in, as shown in Fig. 6,'the

tip of the finger slides along the curved surface' of the ball race andis guided back into the opening between the two ball race members. Fig.7 shows the ball retainer in final osition with the tip of the ballretainer n ers bent over slightl) to better engage an hold the balls inposition.

It will be seen that we have provided a simple, one-.piece ball retainerwhich can be forced into position after the ball race members have beenassembled and which takes u very little room, enabling the ballato be amost touching each other so that practically a full set of balls may beused.

We claim:

1. A radial ball bearing construction comprising a plurality of balls,inner and outer all race members and an annular ball retainer having aseries of fingers separating the halls, each finger having a curved edgeportion conforming to one of the balls, and engaging the ball on theside farthest from the axis of the bearing, the lingers of said retainerbeing inscrtablc between the balls after the balls have been placed inposition between the ball race members, the ti of cai-l1 finger being ofSuch width that its engagement with, the lwo balls on each side of itforces it outwardly into the race-wa in the outer ball race member asthe bal ietainer is being pressed into place, the engagement of the tipof the linger with the raceway forcing it inwardly again as the retaineris finally pressed into place, the ti s of said fingers being wider thanthe mid e portions thereof, the middle portions of said fingers beingneed a substantial distance from thevouter all race xine'lnber.

2; A radial ball bearin construction comgrsing a plurality of ba ls,inner andlouter al1 race members and an 'annular ball re-v tainer ha l'a series of lingers separating thev balls, eac'l1 finger havingA acurved edge portion conforming to one of the balls, and A engaging theball on' the side farthest from .the axis ofthe bearing theA lingers. ofsaid outer ball raoe member` as the ball retainer is being pressed intoplace, the engagement of the tip of the finger with the race-wa forcingit inwardly a ain as the retainer xs nally pressed into p ace, the ti ofs'aid fingers being wider. than the middl e ortions thereof, the middleportions of sai fingers being spaced a substantial'distance from theouter ball race member, the tips of said ingersbeing nearer the axis ofsaid bearing than the middle portions thereof.

In witness whereof, we have hereunto sub scribed our names.
